What Does Vapor Fraction Mean?
Vapor fraction refers to the ratio quantity of the gaseous component present in a mixture of two or more physical states.
The higher temperatures of a metallic surface can propagate an increase in the vapor fraction of the metallic environment because more vapor is formed at higher temperatures. However, an increase in the vapor fraction correlates to an increase in pressure. This increases the likelihood of material fatigue, metal degradation and vapor corrosion.
